1. An apparatus, comprising:
- a transmitter configured to transmit a service request;
a receiver configured to receive acknowledgement information confirming a successful transmission of said service request; and
a controller configured to, if no acknowledgement information has been received after said service request has been transmitted, setting an interval for an attempt to retransmit said service request, randomly choose a timepoint from said interval, wherein the controller is configured to set a length of said interval, wherein said interval length is set responsive to a number of unsuccessful service request transmission attempts and a priority class of said service request, said apparatus being a wireless client device,said transmitter being configured to retransmit said service request at said timepoint.
